Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of three different doses of intrathecal fentanyl and sufentanil for labor analgesia.
To compare the duration of analgesia and incidence of side effects of three doses of intrathecal fentanyl (25 micrograms, 37.5 micrograms, 50 micrograms) with three doses of intrathecal sufentanil (5 micrograms, 10 micrograms, 15 micrograms). ⋯ Intrathecal sufentanil produced analgesia of longer duration than fentanyl for all doses studied. The duration of pruritus with sufentanil was also longer.

Randomized Controlled Trial Comparative Study Clinical Trial
Prophylactic antiemetics for laparoscopic cholecystectomy: a comparison of perphenazine, droperidol plus ondansetron, and droperidol plus metoclopramide.
To compare the prophylactic administration of ondansetron plus droperidol, droperidol plus metoclopramide, and perphenazine to determine effects on postoperative nausea, vomiting, and sedation after laparoscopic cholecystectomy. ⋯ These three drug regimens are equivalent for antiemetic prophylaxis before laparoscopic cholecystectomy.

Randomized Controlled Trial Clinical Trial
Oral clonidine premedication does not prolong analgesia after herniorrhaphy under subarachnoid anesthesia.
To determine the effect of oral clonidine premedication on duration of sensory and motor block, postoperative analgesia, hemodynamic stability, sedation, and respiratory parameters after subarachnoid anesthesia (SA). ⋯ In healthy patients, premedication with oral clonidine provided useful sedation and anxiolysis and stable hemodynamics, without prolongation of sensory and motor block. Side effects occurred only with clonidine 5 mcg/kg. Thus, a dose of 2.5 mcg/kg is recommended.

Randomized Controlled Trial Clinical Trial
Alfentanil decreases the excitatory phenomena of sodium methohexital.
To evaluate the effects of alfentanil or lidocaine on the excitatory phenomena (myoclonus, cough, hiccough) caused by methohexital anesthesia and on the hemodynamic changes induced by retrobulbar block. ⋯ A small dose of alfentanil (5 micrograms/kg i.v.) decreases myoclonus and cough induced by sodium methohexital anesthesia i.v., resulting in improved quality of induction of anesthesia. Alfentanil also attenuates the cardiovascular responses caused by placement of a retrobulbar block.

Randomized Controlled Trial Clinical Trial
An intravenous fluid bolus is not necessary before administration of intrathecal fentanyl for labor analgesia.
To determine if an intravenous (i.v.) fluid bolus is necessary to prevent any possible hemodynamic sequelae after administration of intrathecal fentanyl in laboring parturients. ⋯ Intrathecal fentanyl produces only minimal hemodynamic changes with or without prior fluid administration.
